Abstract
A vascular catheter includes a blade tip at its distal end. In the specific embodiments, a blade is mounted within the blade tip and a mechanism provided for extending the blade transversely when the blade tip is located within a region of stenosis. By extending the blade and axially translating the catheter so that the blade forms an incision within the region of stenosis, improved angioplastic treatment can be achieved.
